Which statements describe an ideal gas?
Select all the correct answers.
A. The average energy of the particles changes as collisions occur.
B. The particles are in constant motion.
C. Particles both attract and repel each other.
E. The average energy of the particles depends on the temperature.
F. The volume of the particles doesn't affect the behavior of the gas.

Respuesta :

Answer:

B, D, E.

Explanation:

Ideal gases have perfectly elastic collisions with no energy lost. The particle size is insignificant compared to the volume, and the average energy of the particles depends on the temperature.

Considering the deginition of ideal gas, the correct answers are the options:

B. The particles are in constant motion.

E. The average energy of the particles depends on the temperature.

F. The volume of the particles doesn't affect the behavior of the gas.

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

In other words, an ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

This is, an ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces. An ideal gas can be visualized as a collection of perfectly hard spheres that collide but otherwise do not interact with each other. Its kinetic energy is directly proportional to temperature.

Then, the correct answers are the options:

B. The particles are in constant motion.

E. The average energy of the particles depends on the temperature.

F. The volume of the particles doesn't affect the behavior of the gas.
